My experience is, the only way to bend them well, is to take them out of the heel and use a ski pole and vice.  Ive ridden these bindings for years.  My favorite thing to do is to just remove the brakes all together for my fatty's.  I've never been able to get a bent pair to work properly anyways, no matter how good the bend job.  Anyways, when the brakes are removed entirely, it makes the binding maybe a dozen or so grams lighter and unlike salomon bindings, the brake interface is not required for proper binding use.  my 2cents
